If the water feed to the building is plastic, then the connection to the metal piping becomes a bonding connection. This is not part of the grounding electrode system and can be anywhere along the pipe. Jumpers across non-conductive parts are required.

250.52 Grounding Electrodes.
(A) Electrodes Permitted for Grounding.
(1) Metal Underground Water Pipe. A metal under-
ground water pipe in direct contact with the earth for 3.0 m
(10 ft) or more (including any metal well casing effectively
bonded to the pipe) and electrically continuous (or made
electrically continuous by bonding around insulating joints
or insulating pipe) to the points of connection of the
grounding electrode conductor and the bonding conductors.Interior metal water piping located more than 1.52 m (5 ft)
from the point of entrance to the building shall not be used
as a part of the grounding electrode system or as a conduc-
tor to interconnect electrodes that are part of the grounding
electrode system.

Home Inspection: "A business with illogically high liability, slim profit margins and limited economies of scale. An incredibly diverse, multi-disciplined consulting service, delivered under difficult in-field circumstances, before a hostile audience in an impossibly short time frame, requiring the production of an extraordinarily detailed technical report, almost instantly, without benefit of research facilities or resources." - Alan Carson

It was jumped. I am home inspector in illinois I have seen this more and more and keep on writing it up . I was just curious what the max. feet away the grounding electrode could be. I know it has to be real close These real estate agents get real mad at me to . They always say well it is grounded. They just don't understnd how important it is. I explain why but they are just worried about the deal
